Numerical weather prediction models from regional and global sources currently point to maximum temperatures in Jeddah on August 3 most likely reaching 40–42°C, driven by peak summer heating over the Red Sea, elevated sea surface temperatures near 30–31°C that sustain high humidity and limit nighttime cooling, and steering patterns that favor clear skies with minimal cloud cover. These conditions align with climatological August averages around 37–38°C yet reflect an ongoing early-month warm anomaly noted by Saudi meteorological agencies. Trader consensus, reflected in the 49% implied probability for 41°C or higher, incorporates model consensus while acknowledging typical forecast uncertainty in coastal heat indices two days out. Updated runs from agencies like the National Center for Meteorology and international ensembles will provide the next key data points before resolution.
